Ashby plots help comparing properties and potentialities of natural materials

Evaluation of materials properties for a selected application necessarily requires a method to compare different material sources. This is particularly true in the case of natural materials, those biocompatible and renewable constituents that can be extracted from biologic tissues. Natural materials often come in the form of composites. Just think, for instance, about a humanContinue reading “Ashby plots help comparing properties and potentialities of natural materials”
